View 1 Repliesi have a bounded datagridview with a checkbox column
I want to set to invisible all rows not checked:
For Each oRow As DataGridViewRow In dgMulti.Rows
oRow.Visible = (CInt(oRow.Cells("Checked").Value) <> 0)
Next
But if if have 5 rows and i check last 4 and selection is on 1st row, the 1st row is set to visible = false but still showing
Public Sub View_Rows(ByVal e, ByVal Type)
rowcount = DataGridView1.RowCount
For i As Integer = 0 To rowcount - 1

Im looking for an event that fires after a user enters a tabbed page and after the datagridview on that tabbed page is painted. BUT only fires on the load, not every single time the datagridview is painted. I am making rows in the datagrid invisible to the user based on wether or not a checkbox in the row is checked.
If I do this on the Tab_Enter event it paints the datagrid before I can loop through the records and change the visible property And if I do this on the Datagridview_Paint event it fires everytime the datagrid is painted (I only want it to fire once)

I have a DataGridView in my VB.net Form. I need to make some rows invisible based on a value. As there is not GridviewrowdataBound, I am trying to achieve it as shown in the below Code

When I try to do this I am getting the Uncommitted new row cannot be made visible error.
I am currently using a DevExpress (10.2) Banded GridView within my Visual Studio 2010 project. It works great except I was have an area where I allow the user to choose which columns they want visible or invisible. I noticed that if I make all the columns within a band invisible the band still remains and gives an empty column in my grid. I was wondering if there is some way to automatically

after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. Note that the Gridview columns have NOT been defined at design time.

View 1 RepliesI know that when I add things to the designer in Visual Studio, it has to be generating code for them somewhere. Where do I find the code that Visual Studio creates when I add controls, change properties, etc in the designer?

View 10 Repliesbut it's something I'm pretty consistently needing for the sake of my own sanity, so:If you add a Settings file to any project in Visual Studio, VS provides a GUI making it quick/easy to add a new Setting entry and assign it a Type; at that point the actual code-behind is automagically created with a variable and a property exposing that variable.Can we build our own designers to generate code this way, with a GUI allowing for those quick/easy variable/property assignments?
View 4 RepliesI created a custom datagridview. In the constructor of that datagridview, I set
Me.AutoGenerateColumns = False
and then, declared and added 4 DatagridViewImageColumns and 140
DatagridViewTextBoxColumns by the code
...
Dim dvgCol as New DataGridViewImageColumn
[code]....
But when I add an instance of that datagridview onto a form, in the form.design.vb there are many code defines for each columns and then sometimes adds additional code to create those columns again. Sometime when I delete the datagridview control in the form,that code is not deleted.
I'm trying to make alterations to an existing project, and I've found a project in the solution which is full of generated classes.Problem is, nobody here can tell me what generated them, so I'm pretty much left with pasting one of the classes in here and hoping someone will be able to tell me where they came from.
The solution I'm working on uses Expression Blend 3 and Visual Studio 2008. Dunno if that's relevant, but I'm trying to give as much information as I can think of... As well as this class, which appears in its own file, there's an "SPResults" file, which contains about 5000 lines of accessor classes of this type. Not quite sure why EndCustomer is in its own file...
From what I can see for myself, there's a stored procedure in one of the databases this program links to, and that SP's name is "GetEndCustomers". Something has then created a class called "EndCustomers" to represent the return type of this procedure.
The first part is a function from a class named Database, which returns a collection of the objects in question.
<FunctionAttribute(Name:="dbo.GetEndCustomers")> _
Public Function GetEndCustomers(<Parameter(Name:="Dummy", DbType:="VarChar(1)")> ByVal Dummy As String) As ISingleResult(Of Data.EndCustomer)
Dim result As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod, MethodInfo), Dummy)

So, yeah, can anyone tell me what has been used to generate this class? It could be something in Visual Studio, Expression Blend, SQL Server Management Studio, or some obscure bit of software I haven't even noticed is on the PC. Any clues, anyone?
I want to get a part of the text a webpage, but when i get the source code using a webclient it gives me a javascript on the place where the text I want is. This javascript generates a lot of text, but how I can I let my program get this text?

I'm having a problem using XML literals with a StringBuilder in VB 2008. If I use this code everything is fine.Dim html As New System.Text.StringBuilder
html.Append(<html><body></body></html>)
MsgBox("hello")
Now the problem is I want to wrap HTML around something that is generated in code.
html.Append(<html><body>)
msgbox("nothing happens")
When the HTML doesn't have the corresponding ending tag, it acts like it goes beyond the ) and keeps looking for it.

I moved from SubSonic 2.x to 3.0 and noticed that all my classes are combined into the ActiveRecord.vb(cs) file. Is there a way to have my classes generated individually in a separate folder (DAL) as I was doing with 2.x?
View 2 RepliesI have started with a small project in VB2008 Express which grew to a complex application. I have deployed the application recently discovering it is rather small, and the major issue is that code-generated controls (checkboxes, comboboxes, textboxes) are not displayed as during development. I have declared the code-generated controls in the declaration region, and there are about 250 controls. According to user selection some of the controls are added to a container panel. Now, I am concern that because I declare those as public (static?) variables, it uses much memory and causes the problem in the compiled application. Is that correct that static declared and code-generated controls uses much memory? How to avoid it ? I need the controls as public variables. Is it better to add all 250 controls on the form in designer mode, and use the property Visible (control.visible=True)?

I have a project with requirements to generate a single executable file with no dependencies that will automate the submission of data to a WCF service based on command line parameters passed to it. As a result, I cannot configure the WCF binding and quotas in an App.config file, so I am generating a BasicHttpBinding in code to use when dimensioning the WCF client object.
However, the WCF service accepts the binary data for a relatively small Excel spreadsheet that ends up being around 30kb, so the default configuration settings for the binding's ReaderQuotas are inadequate. My attempts to increase them in code to 1MB, however, have met with failure each time I make a call to the service.[code]...

I am new to vb.net. I created a vb.net script to autogenerate a code. Now, after generating this code, what I want is to determine the validity of this code. for example, a code has been generated now and this code will be valid for 24 hours only.
Below is my script for the auto generation code

The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.
I've written a for loop to generate several new text boxes and numericUpDowns when the application is run.
The text boxes / numericUpDowns are generated with a 2-dimensional array. My question is: How do I handle when the text boxes / numericUpDowns are modified?
If you would like the code, just request it and I'll add it here.
This is my first post. I have just started some serious .NET programming. Can anyone help me understand what is a good, industry standard in developing the VB.NET or ASP.NET applications? Should we use the Automatically generated code by the VStudio or we should be coding manually i.e. handling the datasets, populating the controls etc instead of using the automatic generated code using wizards.
View 12 RepliesMost of my project was imported from an older version of VB (now I'm using 2008). All of the forms had a "Windows Form Designer Generated Code" that I could expand at the top of the form's code. When I created a new form, that was not there, and I found out that in the solution explorer you can "view all files" and expand the form and look at MyForm.Designer and that has the same type of instantiation code. My question is, is there some way to update the old ones so they too do not have that "form designer generated code" at the top?
View 1 RepliesI've got a form with a TabControl. PictureBoxes (containing thumbnails) are added to each TabPage thru a loop. A click event Handler is added for each PictureBox. When a PictureBox is clicked, a new form is created thru code and a PictureBox is added to it that shows the pictures enlarged. What I need is to add another Handler to the PictureBox in the code-generated form so that I can rotate the pictures because some of them (photographs) were taken with the camera at 90 degree angles from vertical. I've tried to come up with a solution but I always run into the problem of the PictureBox on the code-generated form needing to be declared WithEvents before a Handler can be added.
Code for adding PictureBoxes to TabControl:
'Variable p declared public withevents at class level
p = New PictureBox
img = Image.FromFile(Path.GetFullPath(picfile))
